A cytosolic NAD+ -dependent GPDH from maize (ZmGPDH1) is involved in conferring salt and osmotic stress tolerance

Plant glycerol-3-phosphate dehydrogenase (GPDH) catalyzes the reduction of dihydroxyacetone phosphate (DHAP) to produce glycerol-3-phosphate (G-3-P), and plays a key role in glycerolipid metabolism as well as stress responses.
